Jacking drive systemWhy use VFD for jacking?

Electrical jacking systems are typically

powered by special high-slip motors which are

DOL started.

Starting currents are very high with DOL

starting

Mechanical stresses are very high during

starting and stopping.

For jackup vessels with DP, the transition from

DP to jacking may be dangerous due to risk of

blackout when starting the jacking system

Problems to be solved with old design

| Slide 6May 16, 2016

Jacking drive systemBenefits

Standard VFD motors can replace high-slip

jacking motors.

Safe, controlled starting is possible with full

torque and low current.

Integration with the power system and PMS

means that the risk of blackout during starting

is minimized.

Jacking drive systemSystem setup

Variable speed drives in a multidrive

configuration, replacing MCCs.

One inverter per jacking motor.

Inverters are arranged into multidrives by leg

or by layer.

Water-cooled drives are supplied as standard

for the most compact solution. Air cooled drive

is also available

Braking units (chopper) and resistors are

provided to dissipate energy while jacking

down

Jacking drive systemControl system

Control system is based on the ABB 800xA

control platform, in common with other ABB

marine control systems.

Redundant controllers are optional.

Redundant network is provided between

control cabinets and bridge.

Local control panel and bridge remote control

panel are included

Control system setup

| Slide 11May 16, 2016

Jacking drive systemFunctionality

Each motor is controlled to share the load

with the other motors.

Precise leg speed control and a global speed

limit are used to keep the hull horizontal in

cases of uneven rig loading or limited

available power.

Creep speed is provided for easy rig levelling

or adjustment of load distribution.

The jacking speed is automatically controlled

based on the load and the available power.
